WRAPPER CARRIER FOB CIGAR MACHINES.

Application filed March 27, 1922.

To all whom it may concern:

Be it known that I, RUPERT E. RUNDELL, a citizen of the UnitedStates, residing at Brooklyn, county of Kings, and State 0'5 New York, have invented a new and useful Improvement in rapper Carriers for Cigar Machines, of which the following is a specification.

This invention relates to an improvement in a wrapper carrier for cigar machines.

In wrapping cigar bunches by machinery, it is customary to rotate the bunch in a fixed position and to give the wrapper carrier a complex movement which is the re sultant of an approaching movement, a

traversing movement, and an angular move ment, with respect. to the axis of the rotating bunch. This movement of the wrapper carrier is produced by a necessarily complicated construction operated by two cams. After a machine has been in use for some time, a little lost motion develops in the mechanism for giving'the wrapper carrier its complex movement whereby it delivers the wrapper to arotating bunch. Also the bunches vary slightly in diameter. The lost motion and bunch variation referred to sometimes result in excessive tension on the wrapper as it is pulled from the wrapper support by the rotating bunch and wound about the latter. If the wrapper material is very thin, as Sumatra leaf always is, this excessive tension tears and thus destroys the wrapper; and when this occurs the bunch must be re-wrapped. Cigar wrappers must be made of unblemished tobacco leaves, and wrapper stock is therefore expensive and any loss due to destruction thereof is a seri-'- ous matter. The main object of the present invention is the production of a wrapper carrier for cigar machines provided with means whereby wrapper tearing is prevented. With this and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts. Fig. 1 is a side elevation of a device constructed in accordance with the invention, and shown in operative position over a bunch wrapping mechanism Serial No. 547,017.

of well known construction; Fig. 2 is an inverted plan view of the wrapper carrier, partly broken away; and Fig 3 is a sectional view taken on the line 33 in Fig. 2.

In carrying the invention into effect, there is provided a traveling suction head, a perforated wrapper support, and connecting means adapted to permit a relative movement of said head and said'support to prevent wrapper tearing, this movement being produced by the wrapper itself when under excessive tension. The parts above referred to may be varied widely in construction within the scope of the claims, for thepa rticular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. therefore is not to be restricted tothe pre- I The invention cise details ofthe structure shownand de-.

scribed.

Referring to the drawings, t indicates the lower roll, and 5 and 6 indicate thenpper rolls of a bunch wrapping mechanism of well known construction. A wrapper is delivered to a bunch lying in and rotated by this group'oi rolls by means of a wrapper carrier which includes a suction'head 7, generally of the usual construction and operated by the usual mechanism. The lower side of the suction head is open and the opening is covered by a perforated wrapper support- 8, generally of the usual construction but not secured to the suction head in the usual manner.

For the purpose of permitting a provided for uniting the suction head and wrapper support.

This connecting means includes a pair of posts 9 carried by the wrapper support 8 and each provided with a notch 10. These posts lie within the suction head and project through slots 11, formed in bridges 12, cast with and crossing they lower side of the suction head 7.

By an inspection of Fig. 2, it will be noted that the slots '11 are out of parallelism, and the purpose of this arrangement is to control the movement of the support 8 within a definite range.

The notch 10 of each post is. en

gaged by a spring 13, the ends of each of which are anchored to the walls of the suction head by means of a short stud 14: and

nut 15.

These springs normally hold the wrapper support 8 in register with the contour of the suction head 7 at its lower edge but permit it to move, when the wrapper is subjected to excessive tension, to the position shown in Fig. 2, which position is partly indicated by full lines where the wrapper support is shown in full, and partly in broken lines where the wrapper support is broken away. Means are provided for normally preventing relative movement of the head and support; and as shown, this means consists of a series of angul rly disposed rollers 16 located within the suction head 7. These rollers serve three purposes: first, by engaging the wrapper support 8, they hold it very slightly out of contact with the lower edge of the suction head to prevent friction from interfering with the operation of the device; second, by reason of their angular disposition, they normally prevent relative movement of the head and support, supporting the wrapper support at SlX points with just enough friction to prevent movement unless excessive tension on the wrapper exists; and third, they roll with very slight frictional resistance when the wrapper is subjected to excessive tension, and thus permit the wrapper support to move in the direction it should move to avoid wrinkling the wrapper as it is wound about the cigar bunch.

In View of the foregoing, a detailed description of the device is deemed unnecessary and is therefore omitted in the interest of brevity.

What is claimed is:

1. In a wrapper carrier for cigar machines, the combination with a traveling suction head, of a perforated wrapper support, and connecting means adapted to permit relative movement of said head and said support to prevent wrapper tear-i11 2. In a wrapper carrier for cigar machines, the combination with a traveling suction head, of a perforated wrapper support, a pairof notched posts carried by said support within said head, and a pair of springs carried by said head and engaging the notches of said posts.

In a wrapper carrier for cigar machines, the combination with a traveling sue-.

tion head, of a perforated Wrapper support, a pair of notched posts carriedby said support within said head, a pair of springs carried by said head, and engaging the notches of said posts, and a series of angularly disposed rollers carried by said head and engaging said support.

4. In a wrapper carrier for cigar machines, the combination with a traveling suction head, of a perforated wrapper support, connecting means adapted to permit relative movement of said head and said. sup port to prevent wrapper tearing, and means for normally preventing relative movement of said head and said support.

In testimony whereof-I have signed my name to this specification.
